No

Question 29

What are two ways of damage a neuron can suffer during a concussion?

Answer 29

- Snapping a dendrite (permanent) - Stretching a dendrite (Temporary)

Question 30

Name the neurons and the SYSTEMS of the Nervous system it goes through. Example 1: You accidentally lean on the stove and your mother recently put a hot pan on it.

Answer 30

This is a reflex. Perhipheral Nervous System - Sensory Central Nervous System - Interneuron (Spinal Cord) Perhipheral Nervous System (Autonomic Nervous System - involuntary) - Motor Neuron Move hand from hot surface. Ouch!

Question 31

Name the neurons and the SYSTEMS of the Nervous system it goes through. Example 1: You see a ball flying at you.

Answer 31

This is a reaction. Perhipheral Nervous System - Sensory Central Nervous System - Interneuron (Brain) Perhipheral Nervous System (Somatic Nervous System - voluntary) - Motor Neuron Swing your bat!
